PLATFORM ATTACHMENT FOR COMBINED HARVESTERS AND THRESHERS.

SPECIFICATION forming part of Letters Patent No. 759,738, dated May 10,1904. Application filed September 15, 1903. Serial No. 173,276. (Nomodel.)

To all whom it may concern:

Be it known that we, FRANKMCCOWN, AL- vIN G. LOUNDAGIN, and W IL'IONANVILLIAMS, citizens of the United States, and residents of Walla Walla,in the county of Walla TValla and State of Washington, have invented anew and useful Improved Platform Attachment for a Combined Harvester andThresher, of which the following is a specification.

Our invention relates to an improvement in that class of combinedthreshers and harvesters or combined harvesters, as they are sometimescalled, which are provided with a side platform adapted for supportingone or more harvest hands while sacking grain, sewing the filled bags,and delivering the same upon the ground. The details of construction,arrangement, and combination of parts are as hereinafter described,reference being had to accompanying drawings, in which- Figure 1 is aperspective view of a combined harvester provided with our improvedplatform attachment. Fig. 2 is a view illustrating means for adjustingthe wheeled frame to which our platform is attached. Fig. 3 is avertical transverse section of a combined harvester with our improvedplatform attached. Fig. 4. is a side View of aportion of such harvesterand the platform. Fig. 5 is a side View of a combined harvester, showinga modified form of our platform. Fig. 6 is a similar view save that theplatform and the wheeled frame to which it is secured are shown elevatedor in a different position. Fig. 7 is a plan view illustrating theattachment and arrangement of the platform proper which is shown inFigs. 5 and 6. Fig. 8 is partly diagrammatic sectional view showingcertain portions of the modified form of the harvester and illustratingthe relative position of the vertically-adjustable running-wheel of theharvester relative to the opposite wheel when the machine is working onan incline or sidehill.

WVe will first describe that form of our invention illustrated in Figs.1 to 4, inclusive. The axle 1 of the harvester-wheel 2 is journaled inboxes 3, attached to the under side of a frame 4:, consisting of twobars arranged parallel and pivoted at 5 to beam 6, that pro- 5 jcctslaterally from the side of the harvester. Such frame 4 may be adjustedat its free end higher or lower, as may be required, to adapt themachine to run on inclines or side-hills. In other words, the wheel 2will be adjusted higher or lower, according as the inclination of theground is greater or less, and thereby the harvester will be keptpractically level or horizontal. When the machine is running on levelground, the pivoted frame 4 will be horizontal, as will be understood byreference to Figs. 1 and 3. For the purpose of adjusting the free end ofthe wheeled frame 4: any suit able means may be employed, and, as shownin Fig. 2, a rack and pinion subserve this purpose. One of the featuresof our invention is the provision of a curved guide 7, consistingof achannel-bar curved upon the arc of a circle described from the pivots 5of the wheeled frame. The said frame has at its free end a projection orguide-pin that slides in the groove of the channel-bar 7. Bythis meansthe free end of the wheeled frame is held rigidly against lateralmovement and the pivots 5 are correspondingly relieved of undue strain.

Our platform 8 is attached to the outer side bar of the wheeled frame 4,and this attachment is made at the center of the length of the platformand the wheeled frame 4:, and therefore at a point directly over theaxle 1 of the wheel 2. As shown in Figs. 3 and 8, a stirrup or hook 9embraces the outer bar of the frame 4: and is provided with alaterally-projecting arm, which constitutes a stubaxle or short journal10. Instead of the stubjournal 10 the axle 1 maybe made longer and bearranged to carry the outer side of the frame. The journal 10 enters abox 10f, which is attached to the under side of the platform 8. Thelatter is thereby adapted to rock on the journal 10 and is alsosupported thereby at its inner side. It is supported at its outer sideby means of two ropes or chains 11, which are suitably attached to theends of the outer side bar 12 of the platform and pass upward overpulleys, which are journaled in laterally-projecting bars 13, forming arigid attachment of the side of the harvester. From the pulleys 13 theropes or chains 11 pass over pulleys which are journaled in frame-pieces13, that project laterally from the opposite side of the harvester, andthence the said ropes or chains pass down and are secured to theopposite wheeled frame 4*, which is a fixed portion of the main frame.The said ropes are attached to eyebolts, as shown in Figs. 3'and 4, andare taken up or let out, according to the up or down adjustment of thehinged frame on the opposite side of the machine. In practice we proposeto pivot and adjust the frame 4 in the same manner as frame 4.

Asindicated in Figs. 1, 3, 4, the platform is provided with a grain-boxor hopper 00, into which the side spout y of the thresher delivers. Thefilled sacks accumulated upon the rear portion of the platform, asindicated in Fig. 1, will be discharged by means of a tilting devicearranged at that point, but which constitutes no part of our invention.

In the form of our invention illustrated in Figs. 5 to 8, inclusive, buta single rope or chain 11 is employed, the same being connected with abar 14, forming a side attachment of the platform, through the medium ofa cross-piece 15 and'diverging rods 16. (See Figs. 5 and 6.) The axle 1*extends through a boxing 3, attached to the under side of said bar 14,and it also passes intermediately through a vertical bar 17. Since theaxle 1 is journaled in boxes forming an attachment of the wheeled frame4, the said bar 17 and the platform or platform-bar 14 will be carriedup and down, according as such wheeled frame is adjusted higher or lowerat its free end. In Fig. 5 the wheeled frame 4 is adjusted as low aspracticable, and in Fig. 6 itis adjusted as high as practicable, theadjustment being made according to the inclination of the surfaces onwhich the machine is operating. The aforesaid vertical bar 17 issupported by braces 18, which are arranged in triangular relation to itand attached at their converging ends to the platform bar 14. Thevertical bar 17 is further braced by the rod 19, which extends on theopposite side to the left-hand end of the platform-bar 14. That end ofthe latter rests against a vertical bar 20 and is adapted to slide upand down in contact therewith. Such bar 20 is attached to a horizontalbar 21, which is held and adapted to slide in stirrups or keepers 22,that form an attachment of the front portion of the harvester-frame.Such slidable bar 21 and the vertical bar 20 are further rigidlyconnected by means of an inclined brace 23. In both Figs. 5 and 6 theends of the vertical bar 20 are shown connected with the vertical bar 17by means of bars 24. As shown in Fig. 5, when the wheeled frame 4 isadjusted downward at or near its lowest limit the bar 17. and its braces18 and the platform 14 are all carried'down with it; but the verticalbar 20 and sliding bar 21 remain in fixed relation to theharvester-frame so far as relates to vertical movement; but in passingfrom the lower to the higher position, or vice versa, the bar 21 slidesin its keepers and the bar 20 necessarily slides with it. In brief, theplatform 14 is held practically at the same distance above the groundwhatever be the inclination of the latter, and it is held alsohorizontal whatever be its adjustment vertically and whatever be theinclination of the pivoted wheeled frame 4". I

It is apparent that the tension of the rope or chain 11 is appliedequally to the ends of the platform 14 through the medium of thediverging rods 16 and that the platform is further held horizontalthrough the medium of the peculiar arrangement of fixed and movablebraces, &c.

In Fig. 7, 25 indicates a tilting platform pivoted to the platformproper, 14, and adapted to be tilted for discharging filled sacks.

It will be seen that by means of our invention in either form We providea platform upon which harvest hands may stand and upon which sacks ofgrain may be carried and from which they may be discharged and depositedon the ground at intervals, also that the whole weight of the platformattachment is supported upon the drive-wheels and that the thresher ismainly relieved of extra weight upon one side, so that it may be moreeasily kept in vertical position.
